refer from the documentation in the t-code se37.

You can use the below code:

DATA : v_dataum TYPE sy-datum.

CALL FUNCTION 'F4_DATE'

EXPORTING

DATE_FOR_FIRST_MONTH = SY-DATUM

DISPLAY = ' '
FACTORY_CALENDAR_ID = ' '
GREGORIAN_CALENDAR_FLAG = ' '
HOLIDAY_CALENDAR_ID = ' '
PROGNAME_FOR_FIRST_MONTH = ' '

IMPORTING

SELECT_DATE = v_datum

SELECT_WEEK = SELECT_WEEK
SELECT_WEEK_BEGIN = SELECT_WEEK_BEGIN
SELECT_WEEK_END = SELECT_WEEK_END
EXCEPTIONS
CALENDAR_BUFFER_NOT_LOADABLE = 1
DATE_AFTER_RANGE = 2
DATE_BEFORE_RANGE = 3
DATE_INVALID = 4
FACTORY_CALENDAR_NOT_FOUND = 5
HOLIDAY_CALENDAR_NOT_FOUND = 6
PARAMETER_CONFLICT = 7
OTHERS = 8

IF sy-subrc <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

i login in the www.se37.com and enter HELP_VALUES_GET_WITH_TABLE

in the FM input field, and the website popup 'there is no documentaton for function module HELP_VALUES_GET_WITH_TABLE'

is the FM HELP_VALUES_GET_WITH_TABLE not used frequently?
